Ukulungiswa kwemizuzu yokugqibela kukhutshwa kuhlaziyo lwe-Ubuntu 14.04

Mva nje Iqela lophuhliso lweCanonical likhuphe olunye lohlaziyo oluqhelekileyo bahlala befumana iinguqulelo zabo ze-LTS, kule meko ngokuthe ngqo kwi-Ubuntu 14.04 LTS Trusty Tahr.

Ezi Uhlaziyo lunokulungiswa kwe-bug kwaye ngakumbi ii-patches zokhuseleko zekernel yenkqubo.

ICanonical ikhuphe ukulungiswa okutsha kwaye yaxolisa ngale micimbi ingasentla Ezi zenzelwe abanye abasebenzisi zenye yeenguqu zabo ze-LTS Ubuntu.

Kusele kufunyenwe iimpazamo ezintsha ezifanayo zeSpecter ezichaphazela iprosesa ye-Intel's x86. Babizwa ukusilela kwesiphelo seF1 (L1TF) okanye iForeshadow.

Malunga neziphene ezifunyanisiweyo

Uhlaziyo lokhuseleko lweKernel lusombulula ubungozi ngowuphi kubo Ukusilela kwesiphelo seF1, kunye nezinye iimpazamo ezimbini zokhuseleko (I-CVE-2018-5390 kunye neCVE-2018-5391) ifunyenwe nguJuha-Matti Tilli kwi-TCP kunye ne-IP yokuphunyezwa kwe-Linux kernel, enokuvumela abahlaseli ukuba babangele ukukhanyelwa kwenkonzo.

En Isiteyitimenti seCanonical sabelane ngezi zinto zilandelayo:

Kwafunyaniswa ukuba imemori ekhoyo kwindawo yokugcina idatha ye-L1 ye-Intel CPU inokuvezwa kwinkqubo enobungozi eqhuba kwi-CPU.

Obu bungozi busaziwa njengeL1 Terminal Bug (L1TF). Apho umhlaseli wasekhaya kumatshini obonakalayo weendwendwe anokusebenzisa oku ukubonisa ulwazi (inkumbulo evela kwezinye iindwendwe okanye inkqubo yokusebenza kwenginginya). (I-CVE-2.018 ukuya kwi-3.646)

UJuha-Matti Tilli ufumanise ukuba usetyenziso lwe-IP kwi-kernel ye-Linux lwenziwe kwezinye iimeko ekusingatheni iziqwenga zepakethi ezingenayo. Umhlaseli okude unokusebenzisa oku ukwenza ukuba inkonzo ingavunyelwa. (I-CVE-2.018 ukuya kwi-5391)

Njengoko bekuya kuba njalo, Ezi zilungiso ze-bug zokhuseleko ziya kusonjululwa ngokukhutshwa kwezikhuselo kubo.

Ngelishwa, Kwiinkqubo ze-Ubuntu 14.04 LTS (ITrusty Tahr), abasebenzisi baxele oko Ukulungiswa kukwazisile ukubuyela umva kwiiphakheji ze-linux kernel, ezinokubangela “iKernel Panic” edumileyo yabanye abasebenzisi xa beqala ukusebenza kwenkqubo ethile kwiindawo ezithile ze desktop.

Ngelishwa, uhlaziyo lwazisa ukuphinda kubangele ukuphazamiseka kernel ngexesha lokuqalisa kwezinye iimeko, kwaye kuthintele usetyenziso lwejava ukuqala. Olu hlaziyo lulungisa imiba.Siyaxolisa ngokungalunganga.

Ngokunikwa la magqabantshintshi ngabasebenzisi bale nguqulo ye-Ubuntu 14.04 LTS, iCanonical kuye kwafuneka ithathe amanyathelo ngalo mbandela kwaye kufuneka isombulule ingxaki kwangoko.

Ngapha koko Inguqulelo entsha elungisiweyo yeLinux Kernel ikhutshiwe, kubasebenzisi be-Ubuntu 14.04 LTS Trusty Tahr, Ukucela bonke abasebenzisi ukuba bahlaziye izibonelelo zabo ngokukhawuleza.

Ungajonga ingxelo, Kule khonkco ilandelayo.

Uhlaziyo lwe-Ubuntu 14.04 LTS

Njengoko sele kukhankanyiwe, le bug ichaphazela ngokuthe ngqo abo bangabasebenzisi be-Ubuntu 14.04 LTS kubaluleke kakhulu ukuba benze uhlaziyo kwangoko, oku ukunqanda oku kusilela kuchaphazele inkqubo.

Uhlaziyo lunokwenziwa ngokulula.

Bangayenza ukusuka kwisiphelo sendlela ngokwenza le miyalelo ilandelayo:

sudo apt-get update

sudo apt-get upgrade

sudo apt-get dist upgrade

Nje ukuba kwenziwe oku, inkqubo kufuneka iqale ngokuhlaziya iipakeji, kunye nenkqubo yeKernel, yokukhuphela kunye nokufaka ukulungiswa okwenziwe ngokusesikweni.

Ngendlela efanayo ungakwenza oku ngokuzoba, uchwetheze kwisiphelo sendlela:

update-manager

Kwaye oku kuya kubabonisa uhlaziyo oluhambelanayo kwaye baya kwamkela kuphela kwaye bafake.

Emva kohlaziyo lwekernel oluqhelekileyo, kuyacetyiswa ukuba abasebenzisi baqalise kwakhona oomatshini babo kwaye, ukuba kukho imfuneko, baphindaphinde zonke iimodyuli zekernel ezinokufakwa, ukuba bayikhuphile kernel ngesandla.

Ngendlela efanayo, ungajonga kwimiyalelo enikezwe yiCanonical ukuze ukwazi ukwenza uhlaziyo olulula nolukhuselekileyo kwinkqubo yakho.

Ikhonkco yile.
